They then planned to move the project to the Dreamcast console for further development and release, but this was abandoned when Sega announced the end of Dreamcast product line in 2001. At this point, Tecmo decided to release Ninja Gaiden as a launch game for the Sony PlayStation 2 in the United States. Itagaki, however, had other plans; the Team Ninja Leader was impressed with the software development kits for the Xbox and pushed for his team to develop for the Microsoft console.
